Improvements on coronal hole detection in SDO/AIA images using supervised classification
Martin A. Reiss, Stefan J. Hofmeister, Ruben De Visscher +5
We demonstrate the use of machine learning algorithms in combination with segmentation techniques in order to distinguish coronal holes and filaments in SDO/AIA EUV images of the S…
Masses of J^PC =1^-+ exotic quarkonia in a Bethe-Salpeter-equation approach
T. Hilger, M. Gomez-Rocha, A. Krassnigg
We investigate the properties of mesons with the exotic J^PC = 1^-+ quantum numbers. Starting out from the light-quark domain, where the π_1 states are used as references, we predi…
Bending rigidities and interdomain forces in membranes with coexisting lipid domains
Benjamin Kollmitzer, Peter Heftberger, Rudolf Podgornik +2
In order to precisely quantify the fundamental interactions between heterogeneous lipid membranes with coexisting liquid-ordered (Lo) and liquid-disordered (Ld) domains, we perform…
On gluon and ghost propagators in linear covariant gauges
Markus Q. Huber
We compute the gluon and ghost propagators of Yang-Mills theory in linear covariant gauges from the coupled system of Dyson-Schwinger equations. For small values of the gauge fixin…
